Return Value

None

Remarks

The terminate function is used with C++ exception handling and is called in the following cases:

A matching catch handler cannot be found for a thrown C++ exception.
An exception is thrown by a destructor function during stack unwind.
The stack is corrupted after throwing an exception.

terminate calls abort by default. You can change this default by writing your own termination function and calling set_terminate with the name of your function as its argument. terminate calls the last function given as an argument to set_terminate. For more information, see Unhandled Exceptions.

Example

/* TERMINAT.CPP:  
 */
#include <eh.h>
#include <process.h>
#include <iostream.h>

void term_func();

void main()
{

    int i = 10, j = 0, result;
    set_terminate( term_func );
    try
    {
        if( j == 0 )
            throw "Divide by zero!";
        else
            result = i/j;

    }
    catch( int )
    {
        cout << "Caught some integer exception.\n";
    }
    cout << "This should never print.\n";

}
void term_func()
{
    cout << "term_func() was called by terminate().\n";

    // ... cleanup tasks performed here

    // If this function does not exit, abort is called.

    exit(-1);
}

Output

term_func() was called by terminate().
